Short Description
The Shelly 1 Gen4 ANZ is a compact smart switch with potential-free contacts, enabling remote control of electrical appliances via smartphone, tablet, PC, or home automation systems. It operates standalone on a local Wi-Fi network or integrates with cloud-based home automation services.
The device can be accessed, controlled, and monitored remotely from any location with internet connectivity, provided it remains connected to a Wi-Fi router.
It is designed for retrofit installation in standard electrical wall boxes, behind power outlets, light switches, or other space-constrained locations.
Equipped with an embedded web interface, the device allows users to monitor status, configure settings, and manage operations directly through a browser.
The device features a multi-protocol wireless MCU supporting Zigbee and Bluetooth connectivity, ensuring secure and reliable communication. It also supports Matter for seamless integration into modern smart home ecosystems.
Main Features
- Wi-Fi Connectivity: Connects to your home Wi-Fi network (802.11 b/g/n/ax), enabling remote monitoring and control via mobile apps or compatible devices.
- Smart Home Integration: Compatible with Google Assistant, Amazon Alexa, and Samsung SmartThings for voice control and automated routines.
- Local & Cloud Control: Functions independently on a local network and can also be managed through cloud-based platforms.
- Bluetooth Connectivity: Supports Bluetooth and BLE gateways, useful during initial setup and device pairing.
- Zigbee Connectivity: Enables inclusion into Zigbee networks, enhancing flexibility in smart home setups.
- User-Friendly Interface: Includes a physical reset button for manual configuration and troubleshooting.
- Improved Processor: Upgraded hardware with enhanced performance and native Zigbee support.
- Embedded Web Interface: Full-featured web UI for real-time monitoring, configuration, and firmware updates.
- Wireless Protocols: Supports Wi-Fi (802.11 b/g/n/ax) and Bluetooth 5.0 with defined indoor/outdoor range capabilities:
- Wi-Fi: Up to 30 m indoors / 50 m outdoors
- Bluetooth: Up to 10 m indoors / 30 m outdoors
- Dry Contact Output: The relay’s output is electrically isolated—no voltage or current is sourced from the relay itself. This makes it volt-free or potential-free.
- BLE Gateway Functionality: Acts as a bridge between Shelly BLU devices and the broader Shelly ecosystem by receiving Bluetooth signals and forwarding them to the cloud or non-Bluetooth devices locally.
- Wi-Fi Range Extender: Repeats and strengthens existing Wi-Fi signals to expand coverage across larger areas.
- Zigbee Range Extender: Boosts and extends Zigbee signal reach, improving network reliability in larger installations.
- Scripting Support: Full scripting capability using ShellyScript (see Shelly Script Language Features).
- Wide Integration Options: Supports HTTP API, MQTT(s), Webhooks (HTTP/HTTPS), UDP, and third-party integrations.
- Scheduling: Create complex automation schedules based on date, time, weekdays, hours, minutes, and seconds.
- Virtual Components: Use dynamic virtual components for advanced automation logic (Learn more).
- KNX Net/IP Support: Integrate with KNX systems via IP gateway (Documentation).
